North Sea but acts in concert with government SAR operations. The CHC SAR fleet includes three offshore based AS 332L1, along with an EC225 at Statoil's Statfjord field, which can be converted from inter-rig shuttle role to SAR duty role within 15 minutes. Several of the Super Pumas in CHC's Norwegian fleet are prepared for the same quick change to SAR configuration.

On 1 March 1988 a AS332 L1 Super-Puma, LN-OMC had to perform a controlled emergency landing on a cargo ship west of Egersund. No one was hurt. On 16 July 1988 a Super-Puma helicopter had to perform an emergency landing in the North Sea. Everyone was picked up by another helicopter. On 18 January 1996 the Super-Puma helicopter registered LN-OBP was forced to perform an emergency landing in the North Sea some 200 kilometers south-west of Egersund. All passengers survived and the helicopter was still floating 3 days later. Subsequently, the remains of the helicopter went for rebuilding by the students at the aviation technical school at Sola, Norway. On 8 September 1997 LN-OPG, an AS332 L1 Super-Puma, suffered a catastrophic main gearbox failure while flying from Brønnøysund to the Norne oil field and crashed to the sea, killing all 12 aboard. Eurocopter accepted some but not all of the AAIB/N recommendations. Eurocopter's reply can be found in Appendix F to the report (page 265 in the pdf). On 29 April 2016 LN-OJF, an EC225 LP Super Puma, crashed at Turøy in the Bergen archipelago en route to Bergen Airport, Flesland, from the Gullfaks B platform in the North Sea. The helicopter was carrying 11 passengers and 2 crew members, but none survived the crash. Eyewitnesses have reported that everything seemed normal until there was a sudden change in the sound, before the main rotor detached and the aircraft fell down. Due to the crash, all commercial flights – but not search and rescue flights – by EC225 helicopters were grounded immediately by both Norwegian and British civil aviation authorities.
